The R520 "Fudo" could have 300 million transistors

We don’t have the exact number yet, but in a conversation with a source, we were reminded that with every single chip generation ATI ended up with twice as many transistors as the previous chip.

If we take into account that the R420 chip codenamed Loki and commercially known as X800 series ended up with number close to 150 millions of transistors, the 300 million figure may be close to the mark.
